摘要

封面重点介绍了在光化学和酸催化条件下，大麻萜醇（CBG）在有机溶剂中的反应性研究，指出了光激发的 CBG* 在选择性生成 2,2-二取代-铬烷衍生物（绿色路径）中的关键作用。另一方面，在布氏-洛氏酸存在的条件下，两个叔碳基竞争性地生成（I+、II+，橙色和蓝色路径）。最后，在有 BF3*OEt2 存在的甲苯中进行反应时，发现溶剂发生了类似 Friedel Crafts 的烷基化反应（紫色路径）。更多信息，请参阅 Daniele Merli、Stefano Protti 及合作者的研究文章（DOI: 10.1002/cptc.202400157）。

Front Cover: Photochemical Vs Thermal Acid Catalysed Cyclization of Cannabigerol (CBG): An Unexpected Selectivity (ChemPhotoChem 11/2024)

The Front Cover highlights investigations of the reactivity of Cannabigerol (CBG) in organic solvents under both photochemical and acid catalyzed conditions, pointing out the key role of the photoexcited CBG* in the selective formation of a 2,2-disubstituted-chromane derivative (green path). On the other hand, in the presence of Brønsted-Lowry acids, two tertiary carbocations are competitively generated (I⁺, II⁺, orange and blue paths). Finally, when performing the reaction in toluene in the presence of BF₃*OEt₂, a Friedel Crafts-like alkylation of the solvent was noticed (purple paths). More information can be found in the Research Article by Daniele Merli, Stefano Protti, and co-workers (DOI: 10.1002/cptc.202400157).
